Privacy Policy

SpeakEn · Last updated: July 29, 2026

Welcome to SpeakEn ("the App"). We care deeply about your privacy. This policy explains how we handle your data.

1. What we collect

The App follows a "local-first" principle:

2. Microphone permission

Used to record your read-aloud so we can score it. The microphone is active only when you explicitly start recording, and audio is stored on your device temporarily — it is removed when you switch sentences.

3. Speech recognition permission

Used to convert your speech into text for word-level scoring. On iOS this is handled by the system speech service; on Android by the system or Google speech service. Recognition may require a network connection managed by the OS, but the resulting text is used only within the App for scoring.

4. Notification permission

Used to send the daily study reminder at the time you choose. It is off by default and must be turned on by you. We only send practice reminders — never marketing or advertising push.

5. Local storage

Used to save settings, study progress, favorites, score records, and reminder time. The data stays on your device; nothing is uploaded to any server. Uninstalling the App removes all local data.

6. Text-to-Speech (TTS)

Used to read English sentences aloud. Handled by the system speech engine; no third-party service is involved.

7. Third-party SDKs

The App uses these open-source libraries, each with their own privacy practices:

None of these SDKs send user data to the App developer.

8. In-app purchases

The current version offers no in-app purchases, no subscriptions, and contains no paywall or ads.

9. Children

The App is intended for general learners. We do not knowingly collect personal information from children under 13.

10. Your rights

You can clear your study history in Profile → Settings, or revoke microphone, speech recognition, and notification permissions in system settings at any time. Uninstalling the App permanently deletes all local data on your device.
